OLED 512GB Gamma Issues

I spot on some games, like Chained Echoes black background is gray and not true black.

To confirm my guesses I ran this video on my Deck OLED 512GB and portable OLED Innocn 15.6:

On 15-15-15 there is huge differences between those two screens, here are the results:

I think screen on OLED 512GB need some calibration, I hope it will be possible maybe due to firmware upgrade.

I saw something similar on my OLED 256 GB. When the game goes from true black to very light grey the jump is immense. It looks like LCD black and it's kinda unstable and dirty. I'd think it's something to do with the screen but it produces true blacks - e.g. if you call a menu while you see that effect you see that status bar is purely black.

Does it fixed? Near black is greyed out in hdr elden ring after 40% of brightness, but 40% is too low

Back in April there was a SteamOS update that added compensation for Mura effect. It's hard to see but I think this was OP's issue. It's much better now. If you still have issues I suspect there's nothing that can be done.
